Yes sorry about that I remembered it wrong. :) Anyway I think it would be great to optimize it. If I recall right, there was a lot of GC usage in the port.

So I guess you know what it is. But Box2D itself is still used almost everywhere its need. And not port exists aside this.

I think we can create a new branch with API improvements and
additions. I'm not sure what the state of dub support for this is,
apparently branch-based dependencies are now deprecated? I hope we can
do something like this:
# Use the direct C++ Port
dependencies: { dbox: =0.0.2, }
# Use a new D-ified interface which has more features
dependencies: { dbox: d_api:=0.0.2, }
Can we do something like this already with dub?
Andrei's allocators could come in very handy. I'm still unsure how we
can actually hook up a custom allocator, you can't really do things
like $ dmd -alias allocator = mymodule.myallocator.
As for actual behavioral changes, we better start adding unittests then. :)
Btw, there's a Contributions folder in the Box2D distribution which I
haven't ported, it has some cool features like fluids support. I'm not
sure if it's the same as the following video, but the stuff is cool:

From a brief look at the source, it's possible I'll end up
needing turning shapes
from classes to structs and/or hooking it up with a custom
allocator.
I wanted to convert everything into structs, but the problem is the
C++ library used inheritance and virtual methods even though in the
end they end up using all of these objects as stack-allocated objects.
I'm not sure whether we actually have to spawn a lot of shape objects
though (AFAICT few of them ever get instantiated), but if that's true
then converting these to structs might be beneficial.
I expect to need to spawn/destroy objects of varying
shapes very often. (I do plan to try the current version first,
though; it may be good enough)
Good luck!

changes can probably be kept somewhat small), should I open a
pull request or start a fork
(ddbox? ;p)?
We could create a new branch, but for the moment you're probably
better off not writing any pull requests since I will be MIA for a
while (I'm moving very soon). I'll keep you updated.

Same answer! :)
dbox is a complete D2 port of the Box2D game physics library
https://github.com/d-gamedev-team/dbox What is Box2D? == Box2D[1] is an open source C++ physics engine used for simulating rigid bodies in 2D. Box2D is developed by Erin Catto and is zlib-licensed. Box2D is mainly used for game development and interactive physics simulations. Box2D is platform-independent and has no dependencies other than its test-suite which requires the GLFW library. [1] : http://box2d.org/about/ What is dbox? == dbox[2] is a complete D2 port of the Box2D C++ library. dbox targets the latest release of Box2D (currently at v2.3.1) and includes a port of its GUI test-suite. The test-suite includes over 50 unique and interactive examples demonstrating the capabilities of the physics engine. dbox is also a dub package which you can add to your build dependencies right away. See the dub project page[3] for more information. [2] : https://github.com/d-gamedev-team/dbox [3] : http://code.dlang.org/packages/dbox

Hi, nice one. How does it compare to C++ version in terms of performance? Piotrek
